I was about to suggest RAC, when I read your email. I manage 9.2.0.8 RAC
here in NYC and a physical standby in Louisville, KY. I don't know if
Louisville
is 2000 miles from Manhattan, but the standby works perfectly. As a matter of
fact,
last Sunday of each month we switch the roles (3 instances in 4 way cluster
are shut down when the primary takes the role of standby database).
Unfortunately,
with 9.2.0.8 DG broker doesn't work with RAC configurations, so there is no
automatic switch-over. Do you know if Oracle 10g supports DG broker with RAC?
If Osama kills me, I need my database to switch over automatically, so that
I can go to heck without being paged.
